The dry and warm weather will continue today as the strong ridge of high pressure has taken up residence along the Montana/Idaho border. The strengthening ridge will deliver even warmer temperatures than what we saw yesterday. Under sunny skies today, expect afternoon high temperatures into the lower 60’s. Another day of very warm temperatures will promote even more snow melt as the low-level snow pack continues to ripen.

By Thursday, the upper level ridge shifts into central Montana while the deep upper low associated with the western side of the high-pressure ridge moves into California. Compressional heating means even warmer temperatures for Thursday with increasing clouds by afternoon, our high temperatures in the Wenatchee Valley should reach 65 degrees.

Slightly cooler temperatures and mostly cloudy skies for Friday as the weak pacific storm system begins to creep inland, highs in the upper 50’s. By late Friday night, our recent string of dry weather will likely come to an end as a cold front pushes into Northcentral Washington overnight. We have a 30% chance of light rain with overnight lows Friday night around 40 degrees.

Saturday through Wednesday will mark the end of our current mild and sunny weather pattern as a pair of weak storm systems swing into the region from the Eastern Pacific. This will lead to an increasing chance for showers and subtle cooling trend. The first weather system swings into the region Saturday with a 20% chance of showers and highs in the mid 50’s. Sunday will be an in-between storm system day with mostly cloudy skies and high temperatures in the lower 50’s. A second trough begins to swing to the coast and inland Sunday night and Monday with a 40% chance of rain by Monday night and Tuesday with afternoon highs in the mid 50’s and overnight lows in the upper 30’s.
